Referring first to the preferred form of this invention illustrated inFigs. 1 through 6 there is illustrated a stationery folder or envelop 10having one end open and provided with an enclosing flap 12. A flatelastic ribbon 14 of suflicient length to wrap around folder it) isprovided as a separate article as illustrated in Fig. 3. Ribbon 14 isprovided with a metal clip 13 at either end thereof. The metal clip 13may be simply a short length of metal slightly in excess of the width ofthe ribbon as shown Fig. 3 and in which the metal is formed as envelop19 is provided with an aperture 17 at a predetermined position adjacentto the bottom edge 16 of the folder. The aperture 17 is in the form of anarrow slit large enough to permit forcing the metal clip 13 through theaperture while positioned in an endwise relationship. The slit oraperture 17 may thus be slightly enlarged at one end as shown in Fig. 4.After the clip 1.3 has been passed through the aperture 17 it is thenpulled so that clip 13 will lie in a parallel relationship to the slit17. And since the clip 13 is larger in width than slit 17 it will beanchored within the envelop 10 and will provide sufiicient anchorage topermit the ribbon 1 to be pulled upward as illustrated in Fig. 2 for atying or fastening operation. The ribbon 14 may be affixed at itsopposite end by means of a fastening element 13 such as that illustratedin the prior application mentioned above. Element 18 is affixed adjacentto the upper 20 of the folder. Element 18 is provided with a slot 21spaced slightly below the edge 20. Slot 21 is cut or formed and theedges of slot 21 are spaced apart sufficiently to permit ribbon 14 to befitted therein when ribbon 14 is stretched. Slot 21 may be formed with awavy contour so that when ribbon 14 is released it will tend to bunchagainst the edge of slot 21 to thus be retained in its stretchedposition. It is apparent that ribbon 14- may be quickly and easilyinserted into a folder such as folder 117 in which a slot 17 isprepared. It is also apparent that ribbon 14 may be easily removed byturning the clip 13 at right angles to the slit 17 and pushing the clip13 outward. Thus a worn out ribbon 14 can be quickly and easilyreplaced. it is to be noted that when a ribbon 14 has been insertedthrough slit 17 the pull on the ribbon in fastening the ribbon about theenvelop is not a pull directly outward but is a pull at right angles tothe slit 17 thus tending to force the element 13 into a parallelabutting relationship with the inside of the envelop and providingconsiderable strength. Although element 13 is shown in a rounded form,element 13 in being formed or clipped to ribbon 14 may be provided in asquare or other squeezed form without departing from the spirit of thisinvention. Although ribbon 14 has been described as an elastic ribbonthis invention shall include a flexible ribbon 1 2- with little or noelasticity. However in such instance ribbon 14 must be of such a gaugeor thickness that it will fit into slot 21 of the fastener element 18.In this instance due to the wavy contour of slot 21 there will be agripping action on the flexible ribbon as the pull of the ribbon is noteven and there is a tendency for the ribbon to bunch along the irregularprojections of the wavy contour of the slot 21. The ribbon does not pullinto the end of the slot. The ribbon will remain in the position inwhich it is inserted. Although envelop 11 has been described as providedwith a single ribbon l4 afiixed thereto it is apparent that a pluralityof ribbons 14 may be similarly used as illustrated in Fig. 4 withoutdeparting from the spirit of this invention. Figure 4 illustrates apartial section of the envelope showing the ribbon 14 after it has beeninserted into the aperture 17, that is, the end of ribbon 14 providedwith the clip 13. It is to be noted that the ribbon 14 may be insertedthrough aperture 17 by passing the ribbon from inside the folder throughslot 17 and pulling the ribbon until the clip 13 abuts with the innersurface of envelope 10. However a simplified form of mounting ribbon 14is Figure 4, in which the ribbon and clip are identical but in thisinstance the aperture 17 which is slightly enlarged at one end is used.This permits inserting clip 13 from the exterior of the envelope byforcing the end of clip 13 through the enlarged opening and sliding theclip into the position as illustrated and pulling ribbon 14 until clip13 abuts with the inner surface of the envelope.

Referring to Figs. 7, 8 and 9 there is illustrated a further embodimentof this invention in which a cord is provided and in which a pair ofclips 13A are to either end of the cord 14A in Fig. 7. Or a stillfurther modification is illustrated in Fig. 8 in which the cord 14A 'isprovided with a single clip 13A at one end thereof. In eithermodification the cord may be affixed to an envelop as illustrated inFig. 9 in which the elem nt 13A is inserted within a slit 17A asdescribed in the above embodiment and the cord 14A may be wrapped aroundthe envelop to be fastened as described in the above embodiment or to betied to a clip or fastening element as desired. Although the envelop hasbeen described as fastened with a single cord affixed thereto it isapparent that a plurality of cords 14A may be similarly used accordingto the embodiment above illustrated in Fig. 4. In this embodiment cordMA may be an elastic cord or may have little or no elasticity withoutdeparting from the spirit of this invention. Although this invention andprimarily the tying element 14 has been described as associated with anenvelop 10 it is apparent that the invention as described may bepracticed in connection with any package whether it be a complete folderor whether it simply constitutes a pair of sides such as the face 15,Fig. 1 and the opposite face as illustrated in Fig. 2 with anydimensions between these faces as long as element 14 is similarly usedto be wrapped around the package and fastened in the same fashion asillustrated in the drawings. It is also apparent that one or more of theribbons 14 or cords 14A may be afiixed to a package in the same fashionas that described herein to provide the fastening or tying means for thepackage without departing from the spirit of the invention and thisinvention shall be limited only by the appended claim.

What is claimed is:

The combination of a stationery folder, a bonding element and afastening element aifixed to said folder in which said bonding elementis provided with a metal clip at one end thereof and said folder isprovided with an aperture to receive said bonding element, and saidfastening element is formed of a rigid material and is provided with aslot that is open to one side of said element to receive said bondingelement, said metal clip inserted through one end of said aperture to inturn position said bonding element in said aperture, and be retained insaid folder and means to secure said bonding element with said fasteningelement.
